live animal world

Chapter 169 168. See you at the end
The footprints left by the polar bears are clearly visible. Since the wind is not strong and the snow on the surface of the ice sheet has been frozen hard, there is no wind and snow covering the traces left by the polar bears.

The soles of the feet pressed into the snow and creaked, and Su Yun looked back from time to time to be vigilant.

"There are polar bear footprints as a guide, which will be very helpful for our follow-up tracking." While walking, he repaired the zipper of the backpack, and Su Yun stuffed the broken box into the backpack before leaving. The items that were ruined by the arctic wolf Basically, they are all broken, but they can't be thrown here, they can only be taken home and disposed of properly.

After continuing to walk for more than half an hour, I saw icebergs standing in the distance, and the hanging waterfall was frozen. The ice layer at the bottom was particularly thick. It seemed that the ice formed from the bottom, and then spread with the water potential of the waterfall. Go up until the entire waterfall is sealed off.

Su Yun approached, looked at the nearly [-]-meter waterfall and sighed, "We came in the wrong season. If it was summer, we should be able to see the flowing waterfall."

"The waterfall should be produced by melting ice and snow. It seems that there are icebergs behind the mountain."

The white air bubbles are frozen in the waterfall, making the waterfall appear more pure white.Su Yun looked at the salmon frozen in the waterfall. The other party was still alive and well. It seemed that the severe cold came so suddenly that the salmon was frozen in the waterfall without reacting.

Looking back, Su Yun left the frozen area and stood on the coast. The waterfall is only five meters away from the coastline. The ice floe sighed, "Tracking here, the footprints of the polar bear disappeared."

[It's a pity, I thought I would meet a polar bear again soon, who would have thought that the other party would go into the water. 】

[What kind of fish was in the waterfall just now?Why didn't the anchor get it out and use it as a food reserve? 】

The electric inflatable valve has begun to return to normal after being baked by the flame. Looking at the gradually inflated hovercraft, Su Yun said, "The salmon is frozen in the waterfall. The reason why we don't dig it out is a waste of time. I'm afraid that the structure of the waterfall is not stable, and if the ice body collapses due to violent knocking, I can't escape in the first place."

Pushing the hovercraft into the water, Su Yun continued, "Have you seen the situation in this sea area? Ice floes are floating on the sea surface in large and small sizes. It may be because of the obstruction of icebergs that the cold air flow has not completely frozen this area. Therefore, It's warmer here."

"And the ice floes are the favorite area for polar bears, because polar bears can obtain prey by lurking and attacking. Then, the chances of encountering polar bears here are very high."

Wandering in the sea, Su Yun looked around, even if he couldn't find a polar bear, he could meet a seal.

The small ice floe was pushed and bumped into the hovercraft by the sea water, Su Yun had no choice but to push the ice floe with his engineering shovel and move away in the opposite direction.

The fist-sized ice cubes were floating in pieces, as if they were trying to cling to the ice floes, and then grow into bigger ice floes.

Looking down through the azure blue sea, the pitch-black deep sea is like an abyss looking at the lonely boat on the sea. Su Yun didn't feel this, but the audience clamored for Su Yun to adjust the drone lens to observe other places , The deep sea is too dark and scary, the more you look at it, the more you feel suffocated.

Suddenly, Su Yun saw a black shadow on an ice floe in the distance.

Pulling into the camera of the drone, I saw a round-headed seal lying on its side on the ice floe. Its fat body was thicker than a bucket, and it looked around vigilantly from time to time to detect potential dangers.

And behind the ice floes, there are patches of ice continents.

Without Su Yun's words, the audience also saw the spotted seals on the ice floes through the drone, so the barrage was swiped by the wait-and-see.

Su Yun had the same idea as the audience, guarding a prey, waiting for the hunter to come, as long as he has patience, such an obvious piece of fat can definitely attract the attention of the polar bear.

The hovercraft was approaching the ice field not far from the seals. The appearance of Su Yun startled the seals, and they tried to jump into the sea while supporting themselves. This action made Su Yun panic, fearing that the other party would have nothing to do with it.

But fortunately, the harbor seal compared Su Yun's size and found that the opponent had no ability to threaten it. It put away its thoughts of escaping and continued to lie down peacefully on the spot. However, more and more eyes began to stay on Su Yun. .

When he stepped on the ice, Su Yun felt that something was wrong. The ice field under his feet seemed not to be strong. He stomped his feet suddenly, and with a bang, Su Yun sank directly into the sea with one leg.

Pulling his leg up in embarrassment, Su Yun's face turned dark, this time it's good, it doesn't matter if the pants are wet, the key is that the shoes are wet, there is not even a place to burn fire, if you walk barefoot on the ice and snow, you need your feet.

Seal obviously noticed Su Yun's condition, and screamed twice. Su Yun clearly heard the ridicule in this voice, and immediately glared at Seal dissatisfied. Just as he was about to curse, he suddenly saw where Seal was lying. On the side of the floating ice, the water suddenly exploded, and a polar bear slammed its front paw on the ice, and pushed its whole body up with its hind legs.

Before the whole body could stand still, it rushed towards the seal.Su Yun, who was standing in the distance, heard the piercing sound of claws rubbing against the ice, and the sea water was thrown into the air by the movement of the polar bear.

The seal was also taken aback. It was watching the excitement, but it didn't expect that danger suddenly appeared beside it. It screamed in panic, its two flippers supported the ice surface and squirmed, trying to get into it in a hurry. water.

As long as it gets into the water, with its speed advantage, it is impossible for the polar bear to catch up with it.

The next moment, both of them fell into the water and disappeared on the sea in the blink of an eye.

"Fuck!" Su Yun exclaimed this time, never expecting the polar bear to appear so soon.

[Good guy, come as soon as you say, without any preparation]

[Looking at the anchor's current position, the anchor is standing very close to the sea, less than two meters away. Don't brag. If the polar bear attacks the anchor, do you think you can avoid it? 】

Where it fell into the water, white bubbles gurgled upwards,

Su Yun looked at the barrage of inquiries, and responded with palpitations, "If the polar bear attacked me just now, I really don't have the confidence to escape."

"Just now, my eyes were always on the seal, so I didn't observe the surrounding environment. In addition, the polar bear was in the water when it attacked the seal, and the color of its fur was too similar to the color of the ice floe. If the polar bear exposed its back, Floating on the sea, if you don’t look carefully, you would really think it is an ice floe.”

"Fortunately, the polar bears were targeting the fatter seals, not me."

But the more Su Yun thinks about it, the more he criticizes himself in his heart, the cheat with such a good affinity is not well used!If the polar bear really attacked him, it would be over. Next time, you must carefully observe the surrounding environment to make sure that there are no lurking animals within a [-]-meter radius.

Just as he was thinking, the polar bear appeared on the water again, but it came up alone.

Su Yun retreated quickly. If the polar bear really wants to attack it, it seems that Su Yun really has no good way to escape, because the surrounding area is full of ice fields, and the ice surface is not firm. Even if he jumps into the sea, he can throw it away with his own speed. You can drive a brown bear but you can't get rid of a polar bear.

The polar bear who boarded the ice floe just glanced at Su Yun and ignored him.

He shook his body, trying to shake off the sea water on his body, then lay down on the ice floe and began to rub the excess water on his hair to remove the salt essence in the water.

Su Yun stood watching from a distance and said, "That's the trick. Brown bears have used it before. It is to remove the salt from the hair and make the hair more warm."

"Polar bears have two layers of fur, the outer layer is 5-15cm longer, and the inner layer is short and dense."

The polar bear took a look at Su Yun, then walked to the distance, and Su Yun quickly followed.

Following behind the polar bear, Su Yun began to think about how to get close to the other party. If he couldn't get close to the other party, he could only watch the polar bears prey from a distance. After all, the system task did not clearly stipulate that the polar bears must be photographed hunting at close range.

After a pause, Su Yun continued the topic just now and said, "Actually, polar bears are not white as we see them with the naked eye. They are black!"

"The reason why we can see each other's hair is white is because its outer hair is made of keratin, and its hair is hollow. When sunlight hits their fur, some photons will be absorbed by the hair follicles. Captured and illuminated, the polar bear appears to be white."

"When the temperature rises in summer and the oxygen in the air becomes active, the keratin of polar bears will also turn yellow or brown due to oxidation."

"Our fingernails are made of keratin."

The harbor seal on the ice floes just now looked very big, but when the polar bear jumped up from the water and stood on the ice, comparing the two, it can be seen that although the polar bear is skinny, its neck is still bigger than the spot. Seals are much thicker at their thickest waists.

But compared with other polar bears, the arctic legs in front of me look slender and long, which means that the opponent's body has no fat.

Because a healthy polar bear looks very stocky, just like the polar bear in the aquarium.

Walking on the ice field, as long as you don't stomp your feet violently, you won't have much problem stepping on the ground.It seemed that the polar bear also knew that the ice was not solid, so it didn't turn around to chase Su Yun.

Su Yun threw the soaked boots into the air cushion boat, wrapped his feet with a hat and tied them firmly with a rope, and perfunctorily made a shoe. It was inconvenient, but at least it kept warm.

As for the pants, it doesn't matter, there is a diving suit to keep warm, so it's not a big problem.

The figure of the polar bear looks very bleak, standing still from time to time, or standing upright and looking into the distance to find the target. It has not eaten for a long time. If it cannot get food, it will starve to death or freeze to death. An option will come first.

Looking at the opponent's slender hind legs, Su Yun sniffed and said, "The higher the animal is at the top of the food chain, the more difficult its living environment is."

"Let's take polar bears as an example."

"There is no doubt that global warming is caused by humans, and even slight climate changes may have a profound impact on polar bears' sea ice habitats."

"Global temperatures are warming and icebergs are melting. In the past, polar bear mothers would give birth in ice caves opened by icebergs. However, due to the melting of icebergs, the ice caves are likely to collapse, which is extremely unfavorable to the living environment of cubs."

"Seals also like to live in ice holes, so seals will also become victims. But seals are also the favorite food of polar bears, because most of the fat of polar bears is grown from the fat of seals. Due to the decrease of seals, polar bears eat The difficulty of fat will also increase."

After a pause, he continued, "The Japanese discharged nuclear wastewater into the sea a while ago. The first thing affected by the nuclear wastewater is plankton, and plankton is the food of most fish and shrimp, and fish and shrimp are the food of seals, beluga whales, and walruses." Food, seals and other animals are also the food of polar bears, so one link after another, the toxins slowly accumulate, and polar bears, as the top predators, have the most toxins in their bodies."

"The more top-notch predators, the more limited their numbers are. Siberian tigers are an example!"

"So, a simple act of human beings is a devastating blow to animals."

Shaking his head in disappointment, Su Yun became more and more contemptuous of human beings who, while holding the banner of protecting animals, secretly killed animals.

Walking ahead, the polar bear stopped and stopped, the tip of its nose moved on the ground, and even its footsteps began to become lighter. Su Yun was taken aback, what did he find?

While observing carefully, Su Yun stopped and popularized science, "Although the vision and hearing of polar bears are comparable to that of humans, their sense of smell is extremely sensitive."

"The sense of smell of a dog is dozens of blocks away from that of humans, but the sense of smell of a polar bear is seven times that of a dog!"

"It can even smell 1 kilometer away. It relies on this powerful sense of smell to lock the temporary residence opened by the seals under the ice."

[Aren't seals resting on the ice? 】

[We saw so many seals before, weren’t they all resting on the ice?]

Su Yun shook his head, "The seals will also open up a temporary residence, because it is safer."

"Seals will use their teeth to gnaw on the ice, open up an ice cave, and hide in it. In order to maintain oxygen, they will also open a hole on the ice to breathe. As long as they find danger, they can quickly escape underwater and leave. .”

Pointing to the polar bear who was carefully searching, Su Yun said, "Looking at the appearance of this polar bear, it should be the temporary residence of the seal."

As soon as the words fell, the polar bear, who was still cautious at first, jumped out. The powerful force easily broke through the ice, and then the upper body directly burrowed into the ice.

There were screams and the sound of falling into the water, and then the polar bear failed to return to the ice again.

"Failed again!" Su Yun scratched his head, feeling sorry for the big white bear.

The polar bear licked the blood from its mouth, watched the figure of the seal disappear under the ice, and continued to search for food.

Su Yun found that the opponent's figure seemed to be even more bleak.

　Thank you for the 5000 reward from the secular world, thank you very much!The boss wears more clothes!
